Abstract: PURPOSE: An apparatus for discharging leakage gas of a linear compressor is provided to return only the oil to the oil filled in an airtight container by centrifugal separating the leakage gas from the oil returned from the compressing unit, thereby prevent the oil noise from occurring. CONSTITUTION: An apparatus for discharging leakage gas of a linear compressor includes a coil spring(11) separating the oil from the leakage gas leaked between a cylinder and a piston by the centrifugal force in the middle of an oil return passage(10) for returning the oil passing by the sliding part of the cylinder and the piston to an airtight container, and a gas outlet formed in the oil returning passage for exhausting the leakage gas separated from the oil by the coil spring to the inside of the airtight container.
